Specification forming partof Letters Patent- No. 38,452, datedMay 5 1863.

. machine for making paper bags for which Lettcrs Patent were granted to H. G. Armstrong, October 2, 1860, and my improvements consist, first, in hanging the spindle which" carries the roll of paper to a plate rendered adjustable laterally on the bed of the machine for a purpose explained hereinafter; secondly, in so constructing the plate which carries the pasting device and other appliances, and so securing the said plate to the bed of the machine that it can be adjusted laterally thereon for an object described hereinafter; thirdly, foldingthe continuous sheet of paper by means of a pulley or pulleys, or their equivalents,in com bination with'certain horizontal pulleys, or their equivalents, the sharp edges of the pulleys forming creases in the paper, and the horizontal pulleys, or their equivalents, turn-. ing down the folds determined by the creasing-pulleys, thereby enabling me'to impart an accurate fold to the paper without the aid of the objectionable'former? used in other paper-bag machines, as set forth hereinafter fourt'hly, in so arranging the creasing-pulleys that they can be adjusted laterally in respect to each other and to the paper in the manner described hereinafter, so as to determine the creases in the paper to suit bags of different sizes; fifthly, in certain Idlers for guiding the paper toward the severing device without disturbing the fold or crease determined by the creasing-pulleys; sixthly', in so constructing the revolving bar or striker that it can be adjusted to and from its center of rotation for a purpose fully set forth hereinafter; 'seventhly, in a peculiar arrangement of the revolving striker in respect to certain rollers described hereinafter; eighthly, in a blade having a peculiar movement, described hereinafter, in order to transfer the paste from the paste-roller to the fold at the bottom of the bag; ninthly, in forming on the edge of the blade a beveled projection for the purpose of conforming, or nearly conforming, to the circumference of the paste-roller and of insuring the transfer of proper quantity of paste to the bottom ,fold of the bag; tenthly, in a roller having the angular projecting plates described hereinafter, and.

so combined with the paste-roller that the width of the paste on the latter roller shall be limited in the manner and forthe purpose described hereinafter.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specification, vFigure lis a side view of myimproved machine for making paper bags; Fig. 2, a pla'u'view; Fig. 3, a longitudinal section of part of the machine; Fig.4, part of 3 drawn toan enlarged scale; Figs. 5 and 6, diagrams illustrating a part of my improvements, and Fig.'

7 a view of the end of the bag.

Similar letters refer to similar parts throughout the several views.

The frame-work of the machine consists of two longitudinal beams, A and A, connected together at suitable points by transverse bars and supported by suitable legs, 13 B. To this frame is permanently secured a table or platform, 0. Two plates, D and E, are also attached to the frame, but bynneans of bolts or set-screws passing through oblong slots in the said plates, that their transverse position in respect to the tableG and to each other can be readily adjusted to a limited extent. To the adjustable plate E are secured two standards, F F, in the top of which are recesses for receiving the journals of thespindle G, on which are the two adjustable coneshaped collars a a, the roll of paper being confined between the latter, as described in the patent of H. G. Armstrong, October 2,1860. To the adjustable plate D are secured the two standards H and H in recesses, in the top of which turn the journals of the roller I, one of the journals projecting beyond the bracket 11 so as to receive a disk, J, which revolves in the supply of paste contained in a trough, K, secured to the adjustable plate D. Immediately in the rear of the roller I is a shaft, L, which turns in suitable standards, I) b, secured tothe table 0 G, and on this shaft L are two plain pulleys, M M, the position of which in respect to each other can be readily altered at pleasure. To the table 0, and near the rear end of the same, are secured the'two adjustable plates N and N, each plate having two arms, 0 c, and each arm carrying aroller, 01, which has an upper flange only as seen in Fig.

1. A long metal bar,'P, is suspended near its rear end to. a transverse piece, 6, which is secured to the. table 0, the bar beingvery near to the table without being in actual contact therewith. This bar has at its front enda crossbar, f, which carries the two rollers h h, asimilar cross-piece, f, carrying similar rollers,bein g secured to the bar P at a point near the rollers d. To the rear'end of the bar? is secured the plate Q, which has at its outer edge teeth similar to those on the plate described in the aforesaid patent of Armstrong, and which I term the under tearing-plate. This plate Q is situated between the two rollers R and R, (see Fig. 3,) which turn in suitable standards, it, secured to the side beams of the frame. These rollers have collars or enlargements j j, those of one roller being in contact, or nearly in contact, with those of the other, and an opening, it, in the plate Q permitting this contact of the collars with each other.

' S is the upper tearing-plate, which has teeth similar to those of the lower plate, and which. is secured to a bar, T, the latter being secured to standards 1 l on the beams A A of the frame.

U is the driving shaft, turning in suitable boxes on the under side of the beams A and A, one endof this driving-shaft being furof a bar secured to a balanced arm, q, in such a manner as tobe rendered adjustable thereon, a spindle on which arm. turns in a standard, 1', secured to the frame, motion being communicated to this striker from the spindle of the lower roller, It, by means of the pinion's on the said roller gearing into a cog-wheel, t, hung to a pin on the frame, and gearing into the pinion u on the spindle of the said striker. A second pair of rollers, o and 22, turn in projections on a suitable bracket, 2, which is secured to the inside of the beam A of the frame, and is so arranged that it will allow the striker Y to revolve freely, a small table or platform, 3, being secured to this bracket for a purpose described hereinafter. A third pair of rollers, w and w, turn in standards secured to the beams A and Aof the frame. This second and third pair of rollers are caused to revolve in thedirection pointed out by the arrows bythe system of gearing illustrated in the drawings, or by any other convenient train of wheels communicating with the driving-shaft. It should be understood that ,the.

upper roller of each pair turns in boxes arranged to slide vertically in the several standards, and that these boxes are acted on by set-screws, as illustrated in-the drawings, so that the upper rollers may be forced against the lower rollers with more or less pressure.

To a bar secured to the two beams A and A of the frame is attached a trough, 5, and in the edges of this trough the two rollers 6 and 7 are arranged to turn freely. At the rear of the trough is a shaft, 8, which is arranged to vibrate in standards 9 9, secured to the frame of the machine. Anarm, 10, Fig. 1, is secured to this shaft, and this arm is connected by a rod, 11, Fig. 1, to the pin of a crank, 12, secured to the spindle of the revolving striker Y. Twov other arms, 13 13, are secured to the shaft 8, and in the outer ends of these arms turns a spindle, 14,,to which is secured a blade, 15, of the form best observed on reference to Fig. 4. An arm, 16,-

is secured to one end of the shaft 14, and a pin projecting from this arm passes through a curved slot in a bracket, 17, secured to the frame of the machine. An intermittent rotary motion is imparted to the roller 6 in the direction of the arrow by a pawl, 18, hung to an arm, 19, on the vibrating shaft'S, the said pawl being adapted to the teeth of a ratchet wheel, 20, secured to the spindle of the roller. The roller 7 is held by a pawl, 20, the point of which is adapted to the teeth of the ratchetwheel 21 on the spindle of the said roller. It will be observed, on reference to Fig. 2, that on the surface of this roller 7. are certain angnlar projecting plates 22, which render the roller larger in diameter in. some parts than in others. The object 'of this arrangement will be rendered apparent hereinafter. The only bearing for thejournals of the roller 7 are inclined projections formed onthe edge of the trough, so that the roller by its own weight will always be maintained in contact with the roller 6. The folding-rollers 4 4 turn in suitable projections on the beams A and A of the frame, the projecting spindle of one of the rollers having a pulley, 23, round which, as well as round alarger pulley, 24, on the spindle n of the roller R, passes an endless band, 25.

Operation: The roll of paper to be manufactured into bags is placed on the spindle G between the two cone-shaped rollers a a. From thence the paper is passed over the roller I, one edge of the paper overlappingthe disk J, which, revolving in the paste or gum, deposits a portion of the same on the paper. As regards this portion .t fithe operation it is sim ilar to that set fort-hfin the patent of H. G. Armstrong, granted October 2, 1860. From the roller I the .paper passes beneath the pulleys M, which have the sheet of turning up the desired folds, the latter as they pass the pulleys assuming a vertical, or nearly vertical,

position.

0n referring to the Armstrong patent it will be observed that a roller-havin g a rounded taper from its middle toward its opposite ends is used for causing the continuous strip of paper to assume a concave form, as represented in the diagram Fig. 5. The pulleys M M, however, having sharp edges, impart to the paper two creases (see diagram 6) which determine the position of the folds. The creases made by the pulleys M M remain in the paper and continue to 'bethe welldefined limits for the folds as the paper passes through the machine. The only object of using two pulleys,M M, instead of one is that they may be adjusted on the shaft L'so as to be readily adapted for the 1manufactureofbags of differ,v ent sizes. The tendency of the flanged rollers d d is to turn down the folds raised and determined by the creasing-pulleys M M, so that the paper between the said pulleys and rollers will assume the form represented by red lines, Figs. 1 and 2, the vertical folds formed by the pulleys being gradually bent down, so that the pasted fold shall be overlapped by the unpasted fold. The rollers h h of the cross-barf, as well as thesimilar rollers on. the crossbar j, (both rollers being within the folds,) merely serve to guide the paper as it passcs'throngh the machine. It should be understood that the guide-rollers h h render no assistance in forming the fold, which is accomplished by the vjoint action of the creasing-pulleys M M and horizontal flanged rollers h h, the object of the guide "rollers being simply to prevent any lateral sagging of the paper, an end which they accomplish without disturbing the creases made by the pulleys M. In fact, the guide-rollers h may be dispensed with in making bags from heavy and strong paper, while they maybe used with advantage when bags are made from light and tender paper. By the time the paper has arrived at the plate Q it is formed into a flattened tube, which inclos'es the plate, the two folds being pressed together by a weight, as in the Armstrong patent, (if necessary,) and thereby thoroughly cemented to each other. The tube of paper'surrounding the blade Q passe-s between the rollers R and R, which 1 term the drawing-rollers, inasmuch as they serve to draw the paper toward,

the rear of the machine by a continuous movement. The flattened tube is thus moved until it passes between the rollers 11 and e, which I term the holding-rollers, and when su'flicient length of tube to form a bag of the desired len gth projects beyond the tearingblades the tube is struck from below by the revolving str'ikerY and against the tearingblades, and 'by the Wion of the latter and the striker is instantly severed, the form of the severed end of the tubebeing determined by the form and relative position of the two tearingblades, which are such that at the end of the severed tube one side of the latter will project beyond the other, as described in the ethe machine is in factsimilar to the correspondin g part of theArm stron g machine, with this exception, that in the latter the revolving striker severs the paper with a downward stroke, while in my improvement the striker severs the paper by an upward movement, the

result as regards the, form of the severed end of the tube being the same in both cases.

The severed portion of the tube, resting on the small table or platform 3, is carried forward by the rollers v and o toward the rollers w and w, and thence to the rollers 4 4. The moment the end of the severed tube arrives at the proper position above the rollers 4 4 the plate 15, Fig. 4, descends, and,striking the tube near its severed end, turnsup the projecting end of the same and forces it between the rollers 4 4, which complete the fold, the severed tube passing beneath these rollers and being discharged by the same into any suitable receptacle. Before the last-described operation takes place, however, it is necessarythat paste should be applied to that portion of the end of the severed tube which has to be folded over so as to form the bottom of the bag. It will be observed that the lower end of the plate 15, Fig. 4, is beveled on one side.

Now, when the arms .13 13 are being raised by the action of the crank 12 through the rod 11 and arm 10, the pin which projects from the arm 16 through theslotin tbebraclret 17 will, on

account of the curve of this slot, bring the plate 15, which is suspended to the arm 13,

into the inclined position shown in Fig. 4, the beveled side of the lower end of the plate being in contact with. the surface of the roller 6 and thebevel of the plate conforming, or nearly conforming, to the circumference of the roller,

hence a portion of the paste on the latter must be transferred to the beveled portion of the plate, so that when the latter descends and is in the act of thrusting the end (if the severed portion of the tube between the rollers 4 4, the paste on the beveled portion of the plate must be communicated to the fold about to be completed by passing between the said rollers, the

beveled portion of the plate being of the most convenient form for transferring the whole of the paste adhering to it to the-fold,as'wi l1 be readily observed on reference to Fig. 4. It

will be understood that the roller 6 revolves in a supply of paste contained in the trough 5. The

entire surface of the roller would therefore be covered with paste (more than is required in many instanceslbut for the roller 7 and its angular plates, above alluded to. Now,- on reference to Fig. 2, it will be seen that these plates are so situated at the point where the roller 7 is in contact with the roller 6 that they must scrape away all the paste from the latter roller, excepting-that portion which intervenes between the blue lines as w, and this presents sufficient width of pasted surface, from which the plate 15 can abstract a portion to be transferred to the fold of the bottom of a bag of the width illustrated in the drawings. Suppose a still more contracted space for paste on the roller 6 is desired, when a narrower bag has to be made by the machine, then the pawl 20' is raised and the roller 7 so turned that the angularplates 22 will scrape more of the paste from theroller. It will be understood thatthe holding-rolls a; 'U and the rolls to and to must be'properly arranged in respect to and operate in unison with the pasting and folding device in order that the told may be formed on the bottom of the ba g at the desired moment and in the desired position.- The intermediate rollers, 20 and 20, between the holding-rollers and the pasting device, are used for the purpose of allowing room from the free revolution of the striker and at the same time for conveying the severed sections of the tube to the pasting and folding device. The lateral adjustability of the plate E, which carries the roll of paper, as well as that of the plate D, which carries the pasting device, has been previously alluded to. The importance of this ready adjustability of the two plates will be readily understood by those familiar with paper-bag machines without any lengthy explanation. By so securing the striking-barY to the arm q that it can be adjusted thereon,v

the bar can be moved farther from or nearer to its center of revolution; or, in other words, the circle described by the revolving bar can be increased or diminished at pleasure. It will be seen that the revolving striker must at every revolution pass down between the rollers 10 and o, and must consequently pass the severed sections of tubes traversing between these rollers. It is essential that the bar should in its downward movement not strike the section of the tube held by the rollers 22 1), otherwise that section would be bent down and be incapable of passing between the rollers 20 w. If the revolving bar strikes the rear of the bag held by the rollers 10 w, as it should do, no-

detrimental result can take place. The circle described by the revolving striker should conseq uently be proportionate to the length of the severed sections of paper tube, and, as these sections must vary in length according to thesize of the bag, the importance of rendering the striker adjustable on the arm q will be apparent. One of the most important objects of my improvements, however, has been to dispense with the thick former, or (tube distending and supporting bar of other paper-bag machines, among which maybe mentioned the machine for which Letters Patent were granted to B. F. Rice April 28-, 1 857. The formation of the tube of paper by causing the latter tosurround and its shape to be determined by a former was an objectionable feature, overcometo a great extent in the Armstrong patent, in which the thick former was discharged. In my present improvements, however, the desired end is more eii'ectually accomplished by the combined action of the creasing-rolls and horizontal rolls, the first determining the position of the crease and the latter turning, down the folds determined by the crease,

I wish it to be understood. that I do not desire to claim, broadly, the use of continuously-moving feed-rolls, or a revolving striker, or the employment of rolls for holding the tube of paper while it is being severed but I claim as my invention and desire to secure by Letters Patent as an improvement on the aforesaid patent of H. G. Armstrong 1. Hanging the spindle G, which carries the roll of paper, to a plate, E, so secured to the frame as to be readily adjusted laterally thereon, for the purpose specified.

2. So connecting the plate D, which carries the roller I and the pasting device, to the frame, that the whole may be adjusted laterally on the said frame, for the purpose specifled.

4. So securing the creasing-pulleys M M to the shaft L that they can be adjusted thereon in respect to each other and to the paper, for the purpose described.

5. The rollers h h, secured to the bar 1?, and so arranged as to prevent a lateral sagging of the paper without disturbing the creases made by the pulleys M M.
